Customer Reviews

Megan Cannon

Fantastic! Patrick and crew did an amazing job with our addition from start to finish. He listened carefully to what we wanted, offering opinions and advice based on years of experience. He worked hard to make sure we had the best materials for the best price. He was patient when I asked for new or different things, and was always communicative with changes, if there were any unavoidable delays, and progress on the project. I would absolutely contract with them again.

Opal Avenue Interior Design

I’ve collaborated with CBR on projects and have always been impressed by how organized and detail-oriented they are! They put a lot of focus into planning and ironing out the details ahead of time, which makes the construction process run smoothly and stress-free for everyone involved. Their team brings smart solutions to challenges, works with professionalism, and delivers consistently high-quality results. And from a designer’s perspective, it’s refreshing to work with a contractor who values collaboration and takes as much pride in the process as they do in the finished product! Thank you!

We’ve worked with Chagnon Building and Remodeling for two major home renovation projects: A bathroom remodel and a finishing of the basement. We had excellent experiences both times. The quality of the work is detailed and high. All the crafts workers are skilled and attentive to detail. They are a family run business and easy to communicate with, answer questions promptly, and Problem solve any issues that come up along the way. Highly recommend!
